The mechanism of plasmon-exciton co-driven chemical reaction in electrochemical SERS is revealed, where the incident laser is 785 nm. In the graphene-Ag hybrid system, the Fermi level of hybrid system can be increased eV, due to the existence of graphene. Hence, the G-SERS has more advantages and high efficiency than SERS in the field of surface catalytic reactions. The plasmon–exciton co-driven surface catalytic reactions in electrochemical G-SERS were reported, which demonstrate great advantages for plasmon–exciton co-driven chemical reactions on G-SERS in liquid environments, and which can be potentially applied in the surface spectral analysis in electrochemical environments.
